Daniel Defense A1.5 Fixed Rear Sight - Black Hardcoat Anodized

The Daniel Defense A1.5 Fixed Rear Sight delivers precision elevation and windage adjustments in a bombproof aluminum construction. This mil-spec rear sight maintains zero under heavy use while providing the same sight picture as standard A2 configurations.

What Makes This Different

Unlike stamped steel alternatives, the A1.5 features CNC-machined 6061-T6 aluminum construction with Type III hardcoat anodizing for superior corrosion resistance. The dual aperture system includes both 0.070" and 0.200" peepholes for precision and close-quarters engagement. Positive click adjustments provide repeatable 0.5 MOA increments for both windage and elevation.

Key Features

• CNC-machined 6061-T6 aluminum construction for lightweight durability
• Type III hardcoat anodized finish resists wear and corrosion
• Dual aperture flip design with 0.070" precision and 0.200" CQB holes
